Where to find challenging physics problems (besides textbook) ?

AI Thread Summary
For students seeking challenging physics problems beyond textbooks, resources like I.E. Irodov and contest problems from Physicsbowl, CAP High School Exam, and International Physics Olympiads are recommended. These sources provide a variety of questions that can help prepare for exams featuring complex scenarios, such as combining free-fall and constant acceleration motions. Engaging with these materials can enhance problem-solving skills and deepen understanding of kinematics concepts. The emphasis is on finding problems that are challenging yet relevant to the course material. Utilizing these resources can effectively prepare students for their upcoming exams.

I'm currently taking a Calculus Based Physics course. We have an exam in a few days. Although I understand the material well and have performed many textbook problems, my teacher is known for putting challenging questions on the exams. My Prof. writes his own exams, so they are not based on the book. If anyone can guide me to more challenging physics questions, it would be greatly appreciated. This exam is going to cover 1D and 2D Kinematics: Vectors, Free-Fall, Constant acceleration problems, and Projectile motion.

For example: My prof. stated one challenging problem on the exam is going to be a free-fall kinematics problem which will combine for than one motion. Two separate motions will be involved: 1 Free-fall, and 1 constant acceleration.

Have you tried I.E Irodov?
 
How challenging do you want it? You can try contest problems (Physicsbowl, CAP High School Exam, International Physics Olympiads, etc.). Some of the questions on these exams shouldn't be significantly harder than your course material.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
